but we remain a Nat Gas importer
Maybe net, but not entirely. I was recently surprised to learn a significant portion of Haynesville Shale gas is being exported by BG and has saved the Haynesville from shutting down due to low gas demand and low prices.

Take a look at the following report. I know it is long and detailed but jump to page 14, Figure 6. This shows where the industry sees the most need to increase ability to move Natural Gas. The biggest expected growth is to get more capacity to move Nat Gas to the Northeast.
